The progressive introduction of wavelength division multiplexing throughout the 1990's has resulted in a considerable increase in the capacity of optical fibre transmission networks. In spite of a number of limitations in relation to signal to noise ratio and the physical propagation characteristics, Terabit/s data rates over optical fibre are now becoming possible. The use of WDM techniques is an important tool in the process of restructuring networks in the light of the new services and client layers that are a feature of the latest developments.
